Frequently Asked Questions
What is a Royal Mail OBA account number?
Your Royal Mail OBA (Online Business Account) account number is a unique identifier assigned to your business account with Royal Mail. It is required when setting up carrier integrations, such as connecting your Royal Mail account to Zenstores, so that shipments can be booked and billed correctly.
Where exactly does my OBA account number appear?
Your OBA account number appears in the top right-hand corner of the Invoice tab within your Royal Mail Online Business Account portal. It is displayed alongside your OBA Company Name.
Why do I need to click 'Access Online Business Account' twice?
Royal Mail's portal uses a two-step access flow — the first click takes you to an intermediate page, and the second click confirms access and loads your full account dashboard. Both clicks are required to reach the Invoice tab where your account number is shown.
I can't find the Invoice tab — what should I do?
Make sure you have completed both 'Access Online Business Account' steps before looking for the Invoice tab. If the tab is still not visible, your user account may not have full admin permissions on the OBA. Contact Royal Mail business support to verify your account access level.
Do I need my OBA account number every time I print a label?
No. You only need to provide your OBA account number once during the initial Royal Mail integration setup in Zenstores. After that, Zenstores stores the details and uses them automatically when generating Royal Mail shipping labels.
